Operation principle
A solid steel drive shaft that runs continuously for the full width of the door, wraps the belts on the drums and the folding door
structure is raised. The shaft with the drums is attached to the door frame near the bottom.
Opening Procedure
While holding the door on-off switch, which is located on the control unit, electromechanical drives turns shaft and at the same
time belts attached to drums begins to raise the gates. Side locks, mounted on a door frame on both sides, embraces the gates
and they start to rise. Gate rises to the top with the help of lifting straps and the upper end rigidly attached to the upper lintel.
When doors reaches the predetermined height of the opening dis-connectors on the electromechanical drives stops them.
Closure Procedure
While holding the door on-off switch, which is located on the control unit, electromechanical drive loosens shaft, cables became loose and lifting belts allows the doors to move slowly downward. After landing, side locks presses and fixates doors to
the building , thereby ensuring the security and stability of the gate
Whole doors perimeter is sealed with rubber. Because of the dense, doubled rubber seal with the cloth inside, doors becomes
resistant to any weather conditions!
The chain drive motor located in the aid, in case of power failure or breakdown of the door electromechanical actuators can lift
or lower doors manually. For such situations there is dedicated emergency release lever and emergency lifting chain.

Belt System
The door structure is raised by a special polyester lifting
belts (each one's breaking point is 10,000 kg). Lifting belts at
the bottom of the door are wrapped on the drum in several
places evenly over the entire frame of the gate, that gates
would open evenly and easy.
Belts never entangles, nor makes noise, nor rust (as opposed
to of steel cables). Door lifting belts are perhaps the most
important advantage, because you don't need pulleys - less
parts, less problems, less maintenance! Lifting belts are made

Drive shaft
The shaft is mounted on the bottom panel and runs continuously along the entire width of the door in order to properly
support the system. The drive shaft is driven from the gear
reducers by a dual chain drive system and at the same time
belts attached to drums begins to raise or lower the gates. The
shaft is galvanized to prevent corrosion.

Bifold Hangar Door Electronic Safety Systems:
1. The upper door height switch switches off electric current when ascending gates reaches the
highest point of the opening
2. Side locks, does not let the doors to move and protects against high wind loads while they are
in a locked position.
3. 3 buttons control system (up/down/stop). Two buttons located on control unit allows the gate
to move up or down by pressing and holding them until gate rises or descend.
4. Photo electric cell sensor is mounted near the floor to stop the doors in the event of any obstacle. In case of an obstacle at the range of photo electric sensor (object, human, vehicle etc.)
doors won't descend. (optional function).
5. Warning light and sound signal is needed to alert people at the door operation area. This security system is particularly recommended for doors that will be equipped with a radio remote
control or other remote controls (optional function).

DOOR TRUSSES
There are many ways to strength a bifold door.
Barduva Hangar Doors are provided with an
extra Heavy Duty Truss.
Depending on the door size and wind load requirements we provide two types of trusses,
internal or external, in order to avoid bending's
on your door.
A - INTERNAL TRUSS
Most of the doors are provided with an internal
truss. It gives an extra strength in on the door
frame and nice outside look .
B - EXTERNAL TRUSS
The external truss I usually used in larger doors.
It gives an extra strength to the large frames
without adding extra weight.

Locking Mechanism
The locking mechanism is connecting the shaft with the side locks through steel wires.
When the door reaches the closing point the locking arms (side locks) lock the door with
the frame and seal the door completely. Protecting it from any weather conditions.

INSTALLATION
Qualified Barduva professionals with many years of door installation experience, will install
doors quickly and flawlessly, although Barduva will provide you with detailed step by step instructions, in case you want to install your Fabric doors on your own. Our technical office staff
will be happy to answer all your questions.
Installation possibilities
Bifold Doors can be installed in two ways.
1.
Within the building’s door frame (Figure 9,10)
2.
Or with external frame in front for the building. (Figure 11– 16)
